1. A display apparatus comprising: a lower skin;a honeycomb core formed of honey patterns and coupled to the lower skin;an upper skin coupled to the honeycomb core, such that the honeycomb core is interposed between the upper skin and the lower skin;a fixing member including at least a portion inserted between the upper skin and the lower skin in a vertical direction, and a remainder portion protruded from the upper skin, wherein the fixing member is coupled to the honeycomb core, the upper skin and the lower skin by the inserted portion;a filler interposed between the upper skin and the lower skin, and surrounding the inserted portion of the fixing member, anda circuit including a light emitting diode and fixed on the upper skin by using the protruded remained portion of the fixing member. 2. The display apparatus according to claim 1, further comprising: a first through hole penetrating the upper skin; anda second through hole penetrating the lower skin,wherein the inserted portion of the fixing portion enters a space defined between the upper skin and the lower skin by the first through hole and coupled into the second through hole. 3. The display apparatus according to claim 2, wherein the filler is formed with hollow communicating with the first through hole and the second through hole, and closes the space defined between the upper skin and the lower skin around an extension line connecting the first and second through holes, wherein the filler is formed in a cylindrical shape. 4. The display apparatus according to claim 1, wherein the filler comprises an adhesive containing at least one material selected from the group consisting of acryl resin, urethane resin, ether, epoxy resin, chloroprene rubber, silicon, phenol resin, and melamine resin-based materials. 5. A display apparatus comprising: a lower skin;a honeycomb core formed of honey patterns and coupled to the lower skin;an upper skin coupled to the honeycomb core, such that the honeycomb core is interposed between the upper skin and the lower skin;a fixing member including at least a portion inserted between the upper skin and the lower skin in a vertical direction, and a remainder portion protruded from the upper skin, wherein the fixing member is coupled to the honeycomb core, the upper skin and the lower skin by the inserted portion;a flange extending from an outer peripheral surface of the protruded remainder portion of the fixing member and being contact with an outer surface of the upper skin;a filler interposed between the upper skin and the lower skin, and surrounding the inserted portion of the fixing member; anda circuit including a light emitting diode and fixed on the upper skin by using the protruded remained portion of the fixing member. 6. The display apparatus according to claim 5, further comprising: a first through hole penetrating the upper skin; anda second through hole penetrating the lower skin, the second through hole having a greater diameter than the first through hole,wherein the inserted portion of the fixing portion enters a space defined between the upper skin and the lower skin by the first through hole. 7. The display apparatus according to claim 6, wherein the filler is formed with a hollow having a diameter corresponding to the diameter of the first through hole, and is seated between the upper skin and the lower skin by the second through hole. 8. The display apparatus according to claim 7, wherein the inserted portion of the fixing member is contact with the hollow of the filler. 9. The display apparatus according to claim 7, wherein the fixing member comprises male threads formed at an outer peripheral surface of the inserted portion of the fixing member, andwherein the filler further comprises female threads formed at the hollow of the filler,wherein the fixing member is separably threadedly coupled to the filler by assembling the male threads and the female threads.
